Wholesale PricingThe Range Guard 1-inch Mechanical Gas Shut-Off Valve (P/N 120072, full part number 60-120072-001) automatically cuts the gas supply to protected cooking appliances the moment a Range Guard or Industry Guard kitchen fire suppression system actuates. This is a mechanical valve operated by cable tension. During standby, the valve is held open by tension on a 1/16-inch Badger cable running through the detection network back to the release mechanism. When the system actuates, cable tension releases and an internal spring closes the valve, stopping gas flow to the protected appliance.
Cutting fuel supply at the moment of discharge is critical to the overall suppression strategy. If gas continues flowing to a burner during and after a wet chemical discharge, reignition is a real risk once the agent disperses. The mechanical valve eliminates that risk by shutting off fuel simultaneously with agent release, with no electrical signal required. The 1-inch size serves a wider range of appliances than the 3/4-inch valve, including larger fryers, griddles, char-broilers, and similar equipment with higher fuel demand or larger supply line sizes.

Kitchen suppression systems are pre-engineered systems under NFPA 17A and NFPA 96. Gas valve installation must be performed by a certified Range Guard distributor, in coordination with a licensed gas fitter for the physical pipe connections.
- Confirm Pipe Size: The valve must match the pipe size serving the protected appliance. Confirm pipe size with your system's design documentation before ordering.
- Cable Tension: Proper cable tension is critical for reliable valve operation. A certified technician sets and verifies cable tension during installation and at each semiannual service visit.
- Semiannual Professional Service: A qualified technician tests the valve by manually actuating the system and confirming the valve closes completely and resets correctly.
- Post-Discharge Reset: After any system actuation, the valve must be inspected and reset by a qualified technician before gas service is restored.
How is the 1-inch valve different from the 3/4-inch version?
Both are the same mechanical cable-operated gas shut-off valve in different sizes. The 1-inch valve serves appliances connected to 1-inch gas lines, which typically have higher fuel demand than those on 3/4-inch lines. Always match the valve size to the actual pipe size serving the protected appliance, not the appliance's BTU rating or burner size.
Can one valve serve multiple appliances on the same gas line?
A single valve on a shared gas line will shut off gas to all appliances served by that line when the system actuates. Whether this is appropriate for your installation depends on how the gas piping is configured and which appliances need to be shut off on system actuation. Your certified Range Guard distributor determines the correct valve placement during system design.
What other sizes are available?
Range Guard mechanical gas shut-off valves are available in 3/4, 1, 1-1/4, 1-1/2, 2, 2-1/2, and 3-inch sizes to match a wide range of commercial kitchen gas piping configurations.
